To all 'whom it may concern:

Be it known that I, MATTEO TAMBURINI, a citizen of the United States, residin at Iaterson, in the county of Passaic and tate of New Jersey, have invented certain new and useful Improvements in Loom-Clocks, of which the following is a specification.

This invention relates to so-called clocks for looms and the like machines, and especially looms, its object being to provide la clock which may be readily attached to any loom and which will be so constructed that it will register accurately at all times and be proof against being tampered with by unauthorized persons. l

In the accompanying drawing,

Figures l and 2 are side and front elevations, respectively, showing my clock applied to a loom frame;

Fig. 3 is a front elevation of the clock, partly broken away, a part of the loom frame being also shown' in section;

Fig. 4 is a front elevation, partly in section, of a part ofthe transmitting train without the housing shown in Fig. 3;

Fig. 5 is a plan of the clock.; and

Fig. is a horizontal sectional View on the line 6-6 in Fig. 3 and illustrating a modification.

a is the frame and b the sand roll of a loom, the latter being' suitably rotated by the gearing c. The shaft d ofthe sand roll may have a collar e (Fig. 3) suitably secured thereon, the collar having an interior knurled bushing f or (F ig. 6) the knurled bushing g may be set directly in the end of lthe shaft.

etachably secured to the side of the loom frame is a support h, in the present case being a rectangular elongated block oflwood standing upright and having a cavity z at its lower end and a borevj extending from the cavity clear to the top. The support thus forms a housing. The cavity a' may be provided with a lockable door le. At the top of the housing 'h the dial and pointer are arranged. Of course either of these elements may be the movable one, but I prefer to have the dial iixed and form it on an annulus l which is countersunk into the top of the housing. The pointer will be referred to later, its rotation being-effected by the following transmission train;

In a U-shaped yoke m fixed within the cavity z' is horizontally journaled a worm n whose stem protrudes from the housing and has its end formed as a knurled boss 0 adapted to form a coupling with the knurled bushing f or g, as shown. Secured in the cavity by the screw p is a rotary worm wheel g rotatable on a vertical axis and having a depending hub 1" journaled in the stepbearing s, and also having an upstanding hub t having an internally knurled socket u. A shaft e having a reduced knurled lower end w is coupled with the worm-wheel g b having its knurled portion fitted into the knurled` interior of the hub t, said shaft being capable of being rotated independently of the worm-wheel by elevating it (as by reaching into the cavity upon opening the door la) clear of the worm-wheel. The shaft has a bearing at its upper end in a sleeve m fitted into the upper end of the bore j. The head y of the member constituted by the shaft e includes a disk e on which the pointer 2 is provided, a knurled knob or handle 3 projecting upwardly, and a shank 4 projecting downwardly, the shank fitting a socket in the upper end of the shaft and having a radial pin 6 entering a slot 7 in the shaft.

It will be understood that when the loom is operating the sand roll` will rotate the transmission train and the yardage woven will be indicated bythe pointer 2 with reference vto the dial 1. When it is desired to reset the pointer to zero, the operator opens the door c and upon elevating the shaft or member o to break the coupling between such member and the neighboring member g in the train turns said shaft until pointer 2 registers with zero. If an unauthorized person should attempt to disturb the calculation by elevating and turning the head y of member c, theattempt would be abortive because such manipulation would withdraw in 6 from slot 7 and so uncouple said head rom the shaft; if the head is so disturbed, the weaverhas only to turn the same until the pin again enters the slot 7, which will of course leave the pointer to register the same? as before the mechanism was tampered with.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is In combination, a housing and means therein to measure the progress of a moving element including a transmission train having an upright rotary member normally coupled at its lower end and within the housing with a neighboring member in the train but movable upwardly to disestablish the coupling, said member having an upwardly del0 taohable head normally connected to turn therewith and protruding upwardly from the housing, said head and the top of the housing having a coasting pointer and dial.

In testimony whereof I aHiX my siofnature. 15
